VApplication filed April 29, 19535. Serial No. 28,653,

My invention relates to a beverage dispenser', and the objects of my invention are: First, to provide akdi'spenser of this class whereby the beverages or drinks adapted to be dispensed are displayed in transparent containers through an open portion in the front wall of the supporting cabinet; second, to provide a dispenser of thisclass having a beverage er drink display cabinet provided with a plurality of dispensing cocks or faucets arranged at the front side below the beverage or drink containers and also providedvwith openings contiguous to the cocks or faucets for depositing used cups into the bottom'of the cabinet; third, to provide a liquid dispenser having` a plu rality of mixed liquid containers from which the mixed liquids are adapted to be drawn as desired and which are continuously resupplied with similarimixed liquids as the same is 7ithdraiwi from the mixed liquid containers; fourth,.to provide a dispenser of this class having a plurality of mixed liquid display containers connected with unmixed liquid supply containers 'i'or supplying saidV display containers with the uninixed liquids in proper proportions, which unmixed liquids are mixed before being discharged into the display containers as the liquids therein are periodically witlulrawn; tifth, to provide a beverage dispenser' having a.

plurality of mixed drink containers which,

as the drinks thereinare lperiodically With drawn, are supplied from a single float' valve f `controlled water tank `connected to a continuous source of supply, and by readily refill-able syrup'storage containers, the water and syrup being Ymined .in certain 'proportions at theupper ends of the mixed drink containers the water and syrup are discharged therein by the vacuum produced by the withdrawal of the mixed drinks from said containers; sixth, to provide a drink dispenser having mixed drink storage containers supported at the upper portion-of a containing` cabinet and unit cooling means at the lower portion of the cabinet connected with the respective containers and from whichcooling means the mixed drinks are discharged through cocks or faucets for consumption; seventh, to provide a cabinet for a dispenser of this class at the upper portion of which are supported the display and storage containers and tanks, and at the lower` portion lof which is provided a backwardly extended ice chamber for cooling the liquids,

theice chamber serving as a support for` the operator for refilling the containers or tanks without disturbing'theeustomers or the front of the dispenser in any way, eighth, to provide as a whole a `novelly constructed ibev erage dispenser', and ninth, to providea dispenser of this` class whichv is simple and economical Vof constructionk proportionate to its functions, durable, compact, easily operable, and which will not readily deteriorate or get out of order. y Tvliith these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construcf tion, combination and arrangement of parts and portions, as will be hereinafter de scribed in detail and particularly setforth in the appended claims, reference being` had to the accompanying drawings and to the characters of reference thereon, Whichzform a part of this application, inwhich:

Figure l :is a` front elevational view of my beverage dispenser; lligris a sectional elevational view thereof, taken through LMU of l? ig. 1,sl'1owing certain parts and portions 1 thereof in elevation to facilitate` 'theu illustration; Fig. is aser-tional view thereof' :in plan, taken through Fig. 2, showing certain parts and portions brokenaway and ins-section to facilitate the illustration, `and .lf ig. Lf' is. a .rear View of the lunit water tank with the back wall thereof removed, showing certain portions thereof in section and the connections thereto fragmentarily. i

Like charactersof reference referto simi lar parts and portions throughout the sev eral views ofthedrawings... Y

The cabinet l of` my beverage dispenser is provided at theupper portion ofv its front side with openings la, at or `behind which openings is positioned a corresponding number Vof `vertically positioned, large, transparent, n'iiXed-drink display containers 2. Said containers Q are hermetically sealed at their upper ends by means of covers 3, which are secured against `the upper open ends of said containers inany'conveniei'rt manner such as by bolts, sho\vn in Figs. 2 and 8. Said containers :may be supported at their' llower ends on a-snp port 4;, as shovvn in F 2. At the back side of the containers `2 and near the lower ends thereof is positioned a long` water tank 5 for supplying water to all of the containers 2. Said water tank may also be` supportedon the support et as shown. The tank is connected, by means et' syrup jars or containers 8, also preferably.

transparent, there ,being provided one syrup ]ar 8 for each et the mixed drink containers 2. `The containers 8 are provided with covers 9 having sepai'ate, readily removable,

smaller covers 9a for refilling the containers 8. Each of the containers 2 communlcateby .j means of a conductor 10 with the lower portion of the water tank 5, said conductors extending through the covers 3 oit` the containersfQ. `The .conductors 10 are provided at their lower ends, extending into the water tank, with ball check valves 12 to prevent the return of the water 'from the conductors lO-back into the waterI tank 5. Each of the mixed drink containers 2 similarly communicates, by means of conductors 11, with their respective syrup storage containers 8, thelovver ends of the conductors 11 extending intoithe containers 8 being similarly provided with ball check valves 13 to prevent the return ot the syrup in the conductors 11 to the containers 8. Said conductors 1t)y and l1 Aare .provided at their ends extending through the covers 3 with caps 1d and 1o, respectively, said capsf being provided with discharge orifices of such size asto provide 'for the-discharge oi? the syrup in the containersS. and the Water in thetank 5 into the containers 2 in the proportion of one to vfour, theorices in the caps 111 and 15 being .also dependent directly on4 the relative. viscosities of the water and the syrup. Within the containers 2 at their upperiendszare provided drinkmixing members 16, preferably in the form of tunnels which. are secured to the inner sides of the covers.

Y At the loxverrear portion of thelcabinet 1 is provided a long insulated ice container-17 provided` with a .readily removable cover 18. This cover 18 also serves as a walk or supporting platform for the operator when filling the syrup storage containers l8 from the back` side of the cabinet without interfering inany waywith the customers or the dis- Vpensing operation of the dispenser. i In the ice `chamber 17 ispositioned a plurality `oit cooling coils19, there `being provided `one of suchcoils for `each mixed drink displaycon- .tainer 2. `The upper ends of said coils are connecteckby means of conductors 20, with the lower ends of the `containers 2, while the lower ends of saidy coils are connected, by

means of .conductors 21, with dispensing cocks orfaucets 22 positioned directly below Vthe containers 2 within aV recess 1b built inwardly from the front side of the cabinet 1. In the rear` Wall of the recess 1D of the cabinet 1 is provided a plurality of openings 1c which communicate with the lower end of the cabinet in which is positioned a used cup receptacle 2B for receiving the used cups deposited therein through the openings 1U.

Though `I have shown and described a particular construction, combination and arrangement of parts and, portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope olf my invention the construction, combination and arrangement substantially as set iorthin the appended claims.
